I'm sure you already know that an investment in a
Mavic Air 2 will be almost half of what the Autel Evo 2 will be. And as pointed out there are a lot more accessories available for DJI drones as they own 70% of the market.
In terms of image quality for real estate there is no advantage of one over the other as your real estate agents aren't going to be posting anything higher than 4k footage- if that. The images you shoot that go online will be 96dpi and any printed matter won't exceed 8.5x14 much if at all and only need to be at 300dpi at whatever printed size they make.
I don't know if it matters that much, but the Autel Evo II weighs twice what the
MA2 weighs. However one advantage of the EVO II is it has a variable aperture of f2.8 to f11 just like the
Mavic 2 Pro, while the
MA2 has a fixed aperture of f2.8.
If you're considering the EVO II may I suggest you look at the DJI
Mavic 2 Pro. The one big feature I like about the
Mavic 2 is the TRIPOD MODE. Top speed in tripod mode is 2.5mph. So much easier to control in tight spaces than a
Mavic Air 2 where it's top speed is 11mph and so you have to be very light on the sticks. The
M2P's tripod mode is super smooth. IMO there is nothing worse than trying to edit around accidentally jerky moves while in post. Not sure about the modes on the Autel. An interesting looking drone, for sure. JMO
